Daylight has reliably accompanied mankind since ancient time, a fact that continues to astonish. Intuitively, it promotes the natural rhythm of life and has characterized the development of our sense of vision. Light constantly gives us new images and releases emotions. It controls physical processes and influences our biological clock. The uniqueness and the interaction of human beings, architecture and activities require different lighting moods over the passage of time, which Active Light achieves at suitable moments through changes in intensity, light color and direction.
Active Light Concept
The Three Levels Of Light Effect
Light, natural daylight as well as artificial light, affects man at three levels. Purely visually, it supports our perception, emotionally it affects our mood and the biological effect is directly linked to all physical processes.
Daylight is the original source of light that has always shaped mankind since ancient times and with which he has an elementary connection. Not necessarily visible or perceptible, light with its many facets instead subconsciously influences how we experience the world.
Over the last few years, technology has achieved important milestones in the production, distribution and control of light, thereby broadening the possibilities of artificial light planning in combination with daylight. “Active Light” by Zumtobel reveals this potential and takes into account the special relationship between man and light.
Active Light uses natural light as a role model and brings the necessary dynamics of the light back into people’s everyday lives. This is applied through changes of intensity, light color and direction at the appropriate time, adapted to the respective activity
The approach of Human Centric Lighting (HCL) is increasingly becoming the focus of light planning, which, in addition to visual and emotional building blocks, requires simultaneous examination of biologically active light. By being active outdoors, even on dark winter days, the body receives a high dose of light, which has a positive effect on the hormonal balance and all physical biochemical processes. The more time a person spends in closed rooms, the sooner his biological clock loses its natural rhythm, which can lead to poor sleep quality and health issues. Biologically effective artificial light can support and activate people in indoor areas in addition to daylight.
Social psychologists at the University of Bretagne-Sud point out that the weather situation determines human behavior. In the case of sunshine, we are more open to other people, have higher confidence and hand out our telephone number more quickly than on dreary rainy days. It is also interesting that in this study even a reference to possible good weather for the following days influenced the amount of money given as a tip.
Active Light Links Us Back To Our Roots
Even if today’s society is probably the best networked of all time; people are increasingly losing contact to their biological clock. According to nature, every human being is an individual and brings different individual and personal prerequisites to adapt his organism to new conditions.
Good architecture and lighting design, however, is characterized by the fact that man and his constantly changing living and working conditions are reflected in it. Active Light solutions focus on human centric lighting. They transfer spaces from static passive to a dynamic active state.
The association with a fireplace already had a highly emotional and social function for our ancestors. Light design can release these natural emotions. People come together as before, and are supported in their joint creative work. Perhaps, thanks to the meeting place “fireplace”, creativity is attributed to dimmed light.
Over the past few years, Artificial light has achieved a new degree of design, which allows the requirements of man, space and time to be combined through – the intangible element – light.
With dynamics adapted to the needs, artificial light makes a valuable contribution to stabilizing the natural biorhythm of humans, especially in low-light environments.
The dynamics of natural light are determined by means of technologies such as tunableWhite, which allows continuous variation of intensity and light color from warm-reddish to cold-bluish during the day. Such technology, in combination with the appropriate luminaries and the most modern control system and sensors, provide the user with the right light at the right time in the right intensity.
The positive effect of nature can never be completely replaced by technology. Nevertheless, a study on the effect of artificially created natural scenes suggests a positive effect.
